Solar-powered sports watch

The Casio Pro Trek PRW-35Y-3B is a solar-powered digital watch built for outdoor activity. Its bio-based resin case and strap reduce reliance on petroleum-based plastics while keeping the watch light on the wrist. The black digital display shows month, day and date at a glance. It suits anyone who wants a tough, low-maintenance timepiece for daily wear and adventure.

100-metre water resistance

The mineral crystal protects the dial against knocks and scratches during active use. A 100-metre water-resistance rating means the watch handles swimming and surface water sports without issue. Low-temperature resistance keeps the digital functions reliable in cold environments. Solar charging removes the need for regular battery changes, so the watch stays ready for long periods.

Bidirectional rotating bezel for timing

The bidirectional rotating bezel allows quick elapsed-time tracking without extra buttons. Resin construction keeps the 44.60-millimetre case comfortable during extended wear. A buckle clasp secures the strap firmly on the wrist. Unisex styling makes it a practical choice for a wide range of users and wrist sizes.

Questions about this item

How do I set the time correctly on the solar movement?

Expose the dial to bright light until the charge indicator shows full, then use the crown and buttons to set the home city and time; the watch syncs automatically via radio signal when reception is available.

Will the bio-based resin strap need replacement and how often?

The bio-based resin strap resists sweat and UV, but plan to replace it every two to three years if worn daily in salt water or chlorinated pools.

At what depth does the 100 m water resistance reach its limit during continuous swimming?

The 100 m rating covers surface swimming and snorkelling; sustained pressure at deeper depths or high-velocity water sports exceeds the seal design.
